Sup yall,
I’m looking for some help on getting some print settings for PET-CF. I picked myself up a roll of the Polymaker Fiberon PET-CF17 and I’m looking to make an SL-308 lower out of it eventually. Currently on a Bambu P1S.
I did some research on here through some old posts and through some other sites but I’ve been seeing some conflicting info. Some people printing super slow around 15mms-40mms and others printing at 60 or higher. Bed temps varying between 70 and 100. Nozzle temps between 270 and 300. Cooling fans on and running the entire time or fans turned off like printing PA6-CF.
Anyone got any info?
There are no magic settings that work for all printers in all environments. In general, start at the top end of specified temp range, no fan, and max volumetric flow no more than half the specified max. From there it’s just standard tuning process.
Search the Ark https://fosscad.io/c/ark if you haven’t yet. With PET-CF, you will get a lot of different opinions. PET-CF prints great under a wider arrange of settings, and you won’t really know if the layers adhered until they snap.
When you find the settings you want to try, print something small and see how hard it is to snap along the layer lines. Then adjust. When in doubt, hot and slow with minimal cooling.

Venturing out into engineering filaments should happen after you learn how to tune your printer and filament profile. It will stop you from needing to ask other people how best to print filament on your machine.
